I just used one of these for the first time at Field Day, and a great, easy to use product. I ordered one that Sunday afternoon. It arrived a week later, and went together very easily. I got it working, and it works great, but I had to get a newer model keyboard. My 12 year old keyboard had problems with RF, but switching to my newer keyboard did the job. It has a lot of features, and Steve is very good support on putting it together. One other feature I like is the code practice, where it will send you 5 random letters and you can either listen to it, or type it back, and it will go as fast as you want. This is the best addition I've made to my shack in quite a while. Nice product!

The kit went together easily. I put it in a cast aluminum enclosure to avoid stray RF from my portable antenna. I replaced the on-board small DIN connector with a larger 5-pin connector attached to the enclosure and splurged on the keyboard, getting a special compact model that takes up less room from Jaemco.

The unit works great, although I haven't yet gotten used to typing ahead. Programming is very easy, too. I plan on using the keyboard when I get too tired to send well by hand. Now I have a range of keys with which to send --straight key, bug, paddle, or keyboard.

Assembled and tested in few hours - works fine!
Did few QSO with my 2 HF rigs....no problems...
Had a CMOS Super Keyer 3 before and find K20
more versetile...Probably will order another K10
unit to be able to control speed etc. with pots.

A very interesting idea, well executed and built by a gentleman who is very helpful and easy to deal with.

The kit is well documented, and goes together easily. The IC's seem to be immune/resistant to electostatic discharge and clumsy fingers.

A couple of suggestions for builders:

1. Install the 7805 voltage regulator so that is can be bent over, off the board, and tied to a heat sink. It get's hot!

2. If you are going to use an external speaker, use a variable resistor to control volume, or try several values for R8 - the 100 ohm resistor makes for loud audio on an small outboard speaker.

3. For power, use an AC adaptor or a power supply of some kind. I originally wired this up for use with a 9V battery, and it didn't last long.

Overall, an easy project to complete, worked the first time. Documentation, which can be found on the internet, is excellent.

I would recommend this to those who are interested in sending cw with the keyboard. If you are simply looking for a keyer, another solution may suit you better, because you would need a paddle, a keyboard and this keyer. I think this is a lot of hardware for this application.

I use this to send code on 20 and 40 metres. Hope to work you sometime!

After a painful wait for the (very small) package, i finally got my keyer! It wasn't the Post Office, it just hadn't been mailed. Well, what do you expect for $25?

What you get is a great keyboard/memory/paddle keyer that works as advertised. Back in the early 80's, a friend spent hours trying to get a keyboard keyer working from a QST article and it never worked correctly. This kit went together in no time and has all the options I've ever seen.

The only drawback is that you really need a keyboard to control the keyer, which can be a problem if you have limited desk space.

With less buttons and knobs, it was much easier to package this thing than my original CMOS Super Keyer.
